1. LITERAL EQUATIONS
PRE-REQUISITE

2. Curriculum Vocabulary
Literal Equation (ecuación literal):
A literal equation is an equation with two or more variables.
Example: 𝑦=5𝑥−4
A formula is a type of literal equation.
To solve for one of the variables, use inverse operations.

3. Re-writing an Equation in Slope-Intercept Form
Given an equation such as 3𝑦−7𝑥=5
Step 1: Box the term with the variable 𝑦
3𝑦−7𝑥=5

4. Re-writing an Equation in Slope-Intercept Form
Step 2: Use INVERSE OPERATIONS (OPPOSITES) to move everything outside the box away from the box.
3𝑦−7𝑥=5
+7𝑥=+7𝑥
3𝑦=7𝑥+5

5. Re-writing an Equation in Slope-Intercept Form
Step 3: Use INVERSE OPERATIONS (RECIPROCALS) to move the coefficient away from y.
Distribute the denominator (separate the happy family with love).
3𝑦=7𝑥+5
3𝑦 3 = 7𝑥+5 3
𝑦= 7 3 𝑥+ 5 3
